[Project] Dual-Boot between NF SDcard and Stock No-Rooting

What I want to do is Dual-Boot from the MicroSD card. Meaning the NC Boots to the MicroSD and from there it Decides to Boot to either Nookie Froyo or Un-Rooted Stock. Preferably, with Long Press Home Button to go to Stock and Default being Nookie Froyo. How should I go about this?

I haven't Rooted my Stock because for one B&N updates screw your Root. Another reason is so I can try out B&Ns Updates and see how they Improve their OS. Aswell as the Fact that if I screw over Nookie Froyo I'm not stuck with an inoperable NC for the Duration until I fix it. I can Simply ReFlash a Backup IMG of NF.

(Also there's always the Possibility that B&N will get Netflix, it's a Dream )

Thanks to the Great Half-Hour job by Rookie1 we have a working method.

Also you can try j4mm3r'sBoot Menu or rookie1'sCustomizable u-boot
I will have a Complete All-In-One HowTo for all these methods soon so it's all in one place. Please Look Forward to it.

Not Compatible With Rooted Stock with Clockwork Recovery!
Some have reported they've gotten this to work with CWR but many have stated this doesn't work with it. If you have trouble restore your Backed up u-boot.

Yea, all you need to do is remove the card to boot into stack, or keep it in to boot to that ROM. I would however like to see something like this. I hate removing my card all of the time (yes I complain a lot haha), though I can tolerate. I mainly need a way to use an OS on the SD and still be able to use some of that space for the stock OS when I decide to boot that. Hopefully someone knows what I mean.

I complain also about removing the sdcard as well, maybe it is where it is placed on the nook.

This is about half-an-hour hack job and totally untested. Unfortunately I don't have a SD card handy to test. If you are brave enough, try to replace the u-boot.bin on your nookie froyo SD card using the attached file (remember to backup your original). Pressing Home ('n' button) while boot up should skip booting from SD.

ps the stock ROM will mount 1st partition on SD to /sdcard. If your SD card is nookie froyo, you don't have much space on your 1st partition.

pps This is modified base on my eMMC dualboot code. I've changed the recovery key combo to VolUp + VolDown. If you need to go to recovery and have this u-boot.bin on your SD card, remember the key combo change!

UPDATE: Backed up stock NF u-boot.img and replaced. As-is boot is to SDCard. Boot with home key ("n") pressed is to internal. Seems to work as advertised! Noted that you get the non-stock kernel boot image followed by the stock animation. Is that because it is doing a chroot in there? Is the kernel used the one on the SDCard? Excellent work BTW.
